/* --- Density mode (A.5 / §7.2) — verified rem arithmetic, do not add chrome ---
   RE-RUN 2026-09-01 for the scope row (design §4 / requirement 8). The row is
   NOT extra chrome: it is the same 2.75rem `--he-touch-min` strip the tab strip
   occupied, and the two never coexist (_ensureTabs() bails when the descriptor
   is present), so the totals below are unchanged from the A.5 table.

     card (default) 7.35rem  = padding 1.625 + title 1.4875+0.25
                             + url-row 0.9+0.3125 + snippet 2x0.875x1.55=2.7125
                             + gap 0.0625
     card (density) 5.49rem  = snippet clamp 1 (-1.36) and padding -0.5
     chrome default 13.79rem = search row 4.6 + SCOPE ROW 2.75 (was: tabs 2.75)
                             + results-header 2.75 + results padding 1.0
                             + footer 2.69
     chrome density 11.10rem = the same, footer hidden (-2.69)

   1080p (viewport 60rem after browser chrome; overlay pad 5+2):
     panel   = min(90vh = 54, 60-7) = 53rem
     results = 53 - 13.79 = 39.21rem
     cards   = 39.21 / 7.35 = 5.33  -> 5 full + peek  OK
   768px laptop (48rem) + density (this block):
     panel   = min(43.2, 48-4)      = 43.2rem
     results = 43.2 - 11.10 = 32.10rem
     cards   = 32.10 / 5.49 = 5.84  -> 5 full + peek  OK

   The portal scope additionally renders the Features zone and the type-chips
   row INSIDE the scrolling results region (like the web topic chips), so they
   cost scroll, not chrome; density trims both so the object cards keep the
   same share of the pane. */
